The root cause for the case that "cannot close labview-generated exe file"

Question

Hi All, I have a big program including a lot of things. When I converted it to an exe file, it cannot be closed properly. I used to load the dynamic vi in this program and cannot close it by clicking "X" of the window. Now I have removed that dynamic load but still cannot close the exe. Could anyone give me some advice? Thank you!

Hi Freelance_LV, thank you for your advise, here is a program for a USB dongle. Here are the answers:
for now, questions:
1. how are you closing the EXE? Panel close (X) on the top right corner/stop or exit button on the GUI?
[A] I use (X) on the top right corner but it did not work. But when I use exit button on the GUI it worked.
2. Or are you using a FP Close invoke node?
[A] No
3.how are you handling the event for Panel close or for Stop/exit button?
[A] events are inside a sequence frame
how many loops are running in parallel inside the EXE?
[A] It is hard to tell. I am not the original creator of this code, but the main structure is this: a big "for" loop, inside there are some sequence frame, and some events in one of the frame.
how are you stopping those loops when the panel is closed or a Stop/Exit button is pressed.
[A] the main loop inlcudes some events, sequence frame, and something like this. And there is a subvi from some previous people's work to close USB. 
have you checked if all the loops are closing when you stop the EXE?
[A] Sorry I don't know how to check all the loops are closed.
does this work well when you run the source code?
[A] yes source code can be always be closed well.
have you checked for any errors when yuo stop your EXE?
[A] sorry I don't know how to check for errors?
when you say it cannot be closed properly, there could be two things:
1. the front panel/GUI does not close and it stays there. you cannot perform any GUI actions, or it seems to have hung.
[A] Yes GUI still there. But cannot perform any GUI actions.
2. the GUI closes but you can still it in the task bar below, you will have to use the Task manager to force close the executable.
[A] Not this case.
Thank you very much!
